The present invention facilitates the disassembly and coupling of the filter and the attachment and detachment of the engine when the tissue elements of the lubricant filter used in various internal combustion engines are replaced.

Tissue element exchange oil filter used in the past was many in various forms, but all of them were intended only for the filtration effect, which was not only inconvenient in use, but also complicated in structure, even for skilled caregivers, In many cases, oil leaked out and damaged the internal combustion engine.

For example, although there was one described in Korean Utility Model Publication No. 335 (Notice No. 76-751), this forms a central cylinder at the lower part of the filter cylinder, merges the cylinder through the main through hole, and inserts the filter body into the center at the top. In the cover with the hole, the overflow prevention valve is installed inside the cover, and the tapered pipe part is formed, through the distribution hole, the opening and closing ring is inserted into the coil spring, the coil spring is inserted, and the opening / closing valve with the elliptical side at the bottom There were many shortcomings like the above.

In order to solve the drawbacks of the prior art, the cylindrical tube part is formed in the center of the upper cover, and the central hole is drilled in the center of the bottom of the filter body, and a special fastening nut is used. Once assembled, the filter has a structure of no oil leakage at all, which is very economical value, which will be described in detail with reference to the accompanying drawings.

From the top of the top cover (A), the top cover packing groove (1), the oil inlet (2) and the attachment spiral (D) with the internal combustion engine, the tool holder (3), the direct outlet (4) and the oil supply path (5) to form the cylindrical tube part 8 which fixed the oil outlet 6, the tightening spiral part 7, and the leaf spring F with the fixing pin F ', Insert the filter main body B into which the filter net E and the filter body G are interposed on the projection part I which also served as the pressurizing part I '' support base I 'from the outer upper part, and tightening special nut C. In this case, the simple filter nut (B) is decomposed to disassemble and the tissue element (G) is easily exchanged, and there is no leakage of oil. Referring to the effect of the present invention is as follows.

First, the oil flowing into the upper oil inlet (2) of the upper cover (A) is passed through the filter net (E) to the filter medium (G), the pressurization portion (I '') on the bottom of the filter medium (G) And the pressing portion I '' of the protrusion I serving as the supporting support I 'is pressed against the bottom of the lower end of the filter body G, thereby tightening it closely and tightly.

Therefore, while the oil containing impurities passes through this structure, the mixed oil of impurities passes through the dust filter network (E), and the coarse and large particle sludge or impurities are first filtered and the particles containing less particles are filtered (G). At first, it enters the filter body (G) in the form of a roll type, but when it passes through the pressurizing part, it is tightly closed so that impurities do not pass at all, and only pure and clean oil is filtered and dropped to the ridge (H). Entering the internal combustion engine along the oil supply path (5) through the exit port (6), the oil after this process is a high viscosity clear oil as well as lubrication of the internal combustion engine as well as smooth circulation.

Particularly, when explaining the ease of disassembly coupling and detachment, which is the subject of the present invention, first, the packing to be used in the packing groove 1 of the upper cover A is made of a special raw material that is resistant to heat and insoluble in oil. The front face of the part is wide (diameter 4mm round packing), and the circular packing to be used for the packing groove (C ') of the tightening nut (C) to receive the specific gravity of the force is very thin (1mm diameter round packing). When disassembly and desorption, if only the fastening nut (C) is loosened, the pressure is proportional due to the difference in the specific gravity of the joint area, so the cover (A) is not loosened at all, and only the fastening nut (C) is loosened for easy disassembly. If the effect of the filter body G is no longer sufficient, only the filter body G may be replaced.

As described above, the present invention has a simple and accurate attachment and detachment of the internal combustion engine and the filter, and the structure is made of three stages of the upper cover (A), the filter body (B) and the tightening nut (C) at a low price. As it can be produced, it is economical as well as excellent in filtration method and cooling effect, and only the clean and clean oil can always pass through the filter medium (G) due to the tight tightening effect of the pressurization part (I '') at the bottom of the filter medium (G). It can be a variety of effects, such as to facilitate the circulation of oil to extend the life of the internal combustion engine.

Claims (3)
